    Sammanfattning : This thesis investigated (1) social status and shaming experiences in relation to aggressive behaviour and depression, and (2) gene-environment interactions between two genetic polymorphisms related to the serotonergic system – MAOA-VNTR and 5HTTLPR – and experiences of maltreatment in relation to delinquent behaviour and depression among adolescents. The four included studies are based on questionnaire data from the Survey of Adolescent Life in Vestmanland 2006 (SALVe-2006). LÄS MER

  3. 7. Genetic Structuring and the Evolution of Lekking Behaviour in the White-bearded Manakin, Manacus manacus

    Författare :Lisa Shorey; David McDonald; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Lek Evolution; Manacus manacus; White-bearded Manakin; Genetic Relatedness; Mating Success; Male Characteristics; Behaviour; Biologi; Biology; Biologi; populationsbiologi; Population Biology;

    Sammanfattning : Genetic structuring is common in natural populations. It is important to identify and consider population structure when studying evolutionary processes. Recently, the discovery of genetic structuring in some lekking bird species has opened up new perspectives on our understanding of the evolution of lek mating systems. LÄS MER

  4. 8. Roles of Arginine-Vasotocin and Corticotropin-Releasing Hormone in Stress Responses and Agonistic Behaviour of Rainbow Trout

    Författare :Tobias Backström; Svante Winberg; Lynne Sneddon; Uppsala universitet; []
    Nyckelord :Zoophysiology; arginine-vasotocin AVT ; corticotropin releasing hormone CRH ; stress; stress coping; behaviour; rainbow trout; Zoofysiologi;

    Sammanfattning : The neuropeptides arginine-vasotocin (AVT) and corticotropin-releasing hormone (CRH) are involved in the hypothalamic-pituitary-interrenal (HPI) axis. During stress, the HPI axis is activated and cortisol is released into the blood. In addition to their role in the HPI axis, AVT and CRH also have behavioural effects. LÄS MER

  5. 9. Metabolic alterations in patients with self-inflicted aggressive behaviour

    Författare :Sofie Westling; Lund Psykiatri; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggression; insulin; glucose; glucagon; deliberate self-harm; IL-1beta; leptin; suicide attempt.;

    Sammanfattning : Self-inflicted aggressive behaviour is a cross diagnostic phenomenon of major clinical relevance in psychiatric setting. Accumulating evidence speaks for a role of metabolic and immunological factors in aggressive behaviour. LÄS MER

  7. 10. Dietary L-Tryptophan Suppresses Aggression and Stress Responsiveness in Juvenile Rainbow Trout (Oncorhynchus mykiss) : The Role of Brain Serotonin and Plasma Melatonin

    Författare :Olivier Lepage; Svante Winberg; József Haller; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; serotonin; brain; fish; rainbow trout; Oncorhynchus mykiss; feed; stress; cortisol; melatonin; behaviour; aggression; Biologi; Biology; Biologi;

    Sammanfattning : Juvenile rainbow trout (Oncorhynchus mykiss) fed L-tryptophan (TRP) supplemented feed for 7 days show a suppression of aggressive behaviour along with a reduction in post-stress plasma cortisol levels. However, 3 days of elevated dietary TRP does not have any effects on either aggressive behaviour or post-stress plasma cortisol levels. LÄS MER
